1. In a headlight, a main reflector the upper portion thereof being constructed on a semi-parabolic curve and the lower portion on a horizontal plane below the focal axis of the main reflector, a second curved reflector mounted at the front and upon the horizontal portion of the main reflector, a source of light mounted in a vertical position between the main reflector and the second} curved reflector and means for adjusting the source of light vertically to raise 'ings,

neoaaes and lower it and on a horizontal axis to arrange the source of light either in a vertical or in an inclined position.

2. lln an automobile lamp, the combination with a main reflector, a second reflector, a housing, a sleeve having .a flanged end mounted in said housing and having its inner wall formed with a pair of oppositely disposed pointed bearings, a tube fittin in said sleeve and capable of a vertical an inclined adjustment upon said pointed bearbinding screws in said sleeve engaging the tube to retain it in the proper position, a lamp carried by said tube partially surrounded by the hood shaped second reflector attached to the main reflector.

In testimony whereof ll afiix my signature in the presence of two witnesses.
